Наземные и самолетные телескопы

В последние годы области звездообразования детально исследовались с помощью наземных и самолетных телескопов. Основное внимание приходилось уделять рождению массивных горячих звезд; излучение менее массивных и более типичных для звездного населения (и более близких по массе к Солнцу) объектов было слишком слабым для наблюдений. Возможно, одно из главных достижений обзора, полученного со спутника ИРАС, — пополнение списка очень молодых звезд.

Одной из областей, в которых ИРАС «искал» молодые звезды, было темное облако в созвездии Персея, называемое Барнард 5. Найдено четыре дискретных инфракрасных источника. Ярчайший источник, по-видимому, связан с молодой звездой, которая по размерам и массе близка к Солнцу, но ее светимость в 10 раз больше. Эти характеристики согласуются с моделями звездной эволюции, согласно которым такие звезды примерно первые 100 000 лет имеют очень высокую светимость. Сама звезда для детекторов «не видна». Регистрируемое излучение приходит от пыли, которую звезда нагрела от 30 до 800 К.

В облаке, называемом Хамелеон 1 и

видимом в Южном полушарии, было открыто скопление молодых звезд. В нем насчитывается около 70 точечных источников, хотя некоторые из них являются «звездами поля», не связанными с облаком и просто оказавшимися около луча зрения. Некоторые другие источники слишком скученны, чтобы их можно было анализировать индивидуально. Среди остальных объектов имеются 17 таких, которые подобны недавно образовавшимся звездам в Барнарде 5. Часть из них еше находится в облаке, а другие уже вышли из него, но все еще имеют пылевую «вуаль». 25 других источников представляют собой холодные сгустки вещества, часть из которых, по-видимому, находится на стадии коллапса в звезды.
